CHARLES H. WILLIAMS, JR., OF CHICAGO, ILLINOIS, ASSIGNOR T0 CHICAGORAILWAY EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFILLINOIS.

BRAKE-LEVER STRUT.

To all whom it may concern:

Be it known that 1, CHARLES H. l/VIL- LIAMS, Jr., a citizen of theUnited States, residing at Chicago, Illinois, have invented a certainnew and useful Improvement in Brake-Lever Struts, of which the followingis a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is a side elevation of a fulcrum of myimproved construction, the same being shown in position on a brake beam.Fig. 2 is a plan View of the fulcrum and a portion of the beam to whichsaid fulcrum is attached. Fig. 3 is an enlarged cross section taken onthe line 33 of Fig. 2. Fig. et is an enlarged cross section taken on theline tt of Fig. 2. Fig. 5 is an elevation of a modified form of myimproved fulcrum. Fig. 0 is a plan View of a further modified form ofthe fulcrum. Fig. 7 is an elevation of a further modified form of thefulcrum with parts thereof broken away.

My invention relates to an improved brake beam fulcrum which receivesthe brake lever, and which is formed in mating parts in order that itmay be readily ass-embled and positioned upon the brake beam.

In the various types of solid brake beams now in general use, thefulcrums have been fastened by means of rivets or the like, which passthrough apertures formed through the beam at various distances from theface of the flange of the beam, and the principal object of my inventionis to provide a fulcrum which may be readily located on the revailingtypes of solid beams, regardless o the location of the rivet hole insaid beams.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts hereinafter more fullydescribed and claimed.

As shown in the drawings, my improved fulcrum is constructed in matingparts, each part comprising a plate 1, with the rear end of which isformed integral a head 2, provided with strengthening flanges 3 and ofsuch shape as to embrace and fit snugly upon the flange of the solidbrake beam 4 of the ordinary type. The plates 1 lie parallel toSpecification of Letters Patent.

one another and are formed at angles on the heads 2, and thus the spacebetween said plates, which is occupied by the brake lever, occupies aninclined position relative to the horizontal plane occupied by the brakebeam.

Formed through the outer portions of the plates 1 are alined apertures5, which receive the pin or belt, of ordinary construction, upon whichthe brake lever is pivoted.

Formed integral with the inner faces of the plates 1, adjacent the pointwhere they join the heads 2, are spacing lugs 6, and formed therethroughare apertures which receive a rivet 7 thus rigidly uniting the matingparts of the fulcrum.

The under sides of the rear portions of the heads 2 are provided withtransversely disposed ribs or corrugations 8, and formed in the ends ofsaid heads are notches or recesses 9.

10 designates plates which are positioned on opposite sides of the webof the beam, and the outer faces of the forward end of said plates areprovided with transverse ribs or corrugations 11 which are adapted tointerlock with the ribs or corrugations 8. Formed integral with theforward portions of the plates 10 are lugs 12, which, when the parts areassembled, occupy the recesses 9 in the heads 2. The plates 10 arerigidly fixed on the beam by means of a rivet 13, which passes throughsuitably formed apertures in said plates, and through the usual fulcrumaperture formed through the web of the brake beam. By making theseplates separate from the fulcrum and providing the interlocking jointbetween said plates and fulcrum, said plates can be located at variouspoints on the beam corresponding to the fulcrum aperture therein. Forinstance, the plates which have been positioned on a beam where thefulcrum hole is two and one half inches from the face of the flange, canbe removed and fastened on a beam where the fulcrum hole is two inchesor an inch and three-quarters from the face of the beam, and theinterlocking engagement between said plates and the heads of thetwo-part fulcrum will be maintained regardless of the position of saidplates relative to the face of the flange.

In the form of fulcrum shown in Fig. 5, the rear portions of the heads 2are formed into hooks 13 which engage corresponding hooks 14 on the endsof clips 15, which latter are made in various sizes in order to receivethe rivets used in rigidly fixing said clips 011 the beam, said rivetspassin through the fulcrum holes located at different distances from theface of the flange of the beam.

In Fig. (5, I have shown a modified construction wherein the heads ofthe fulcrum are interlocked with plates 16, each of which is providedwith a series of apertures l7 located at different distances from theface of the flange of the beam, which apertures receive the rivet whichpasses through the fulcrum hole in the beam. By this construction, thefulcrum is placed slightly off center, but not to such a degree as toaffect the successful operation of the brake lever, as the same willaceomn'iodate itself to the fulcrum if the same be placed withinreasonable limits on the beam.

In Fig. 7, I have shown a modified construction wherein the rearportions of the heads are provided with lugs 18 which are normallyseated in recesses 19 formed in clips 20, which are fixed to the web ofthe beam by means of a rivet 21. These clips are made in various sizesin order to accommodate the rivets seated in the fulcrum holes, which,as hereinbefore stated, are formed at various distances from the face ofthe flange of the beam.

A fulcrum of my improved construction is comparatively simple, comprisesa minimum number of parts, and is particularly adapted for universal useon the prevailing types of solid beams wherein the fulcrum holes arelocated at different distances from the face of the flange of the beam.

It will be readily understood that minor changes .in the constructionand form of my improved fulcrum can be made and substituted for thoseherein shown and described without departing from the spirit of myinvention.

I claim:

1. The combination with a brake lever fulcrum, of longitudinallyadjustable members and there being an interlocking engagement betweensaid fulcrum and said members.

The combination with a brake beam, of longitudinally adjustable clipsfixed thereto, and a brake lever fulcrum, there being interlockingengagement between said fulcrum and clips.

l. The combination with a brake beam, of clips fixed thereto, and atwo-part brake lever fulcrum arranged on the beam and engaged by theclips thereon.

5. The combination with a brake beam, of clips fixed thereto, a two-partbrake lever fulcrum arranged on the beam and engaged by theclipsthereon, and means rigidly uniting the two parts of the fulcrum.

(5. A brake lever fulcrum formed in mating parts, and clips havinginterlocking engagement with the two parts of the fulcrum and adapted toengage the brake beam on which the fulcrum is located.

7. The combination with a brake beam, of clips fixed thereon, a two-partfulcrum engaged by the clips, and means for rigidly connecting the twoparts of the fulcrum.

8. A brake lever fulcrum comprising a lever mounting part, and a partfor attachment to the beam, said parts being adjustably connectedtogether, whereby the attaching part is adapted to accommodatedifferently positioned rivet holes.

9. In a brake lever fulcrum, a lever mounting part having fixed relationto the brake beam, and a beam attachment part having adjustable relationto said lever mounting part.

10. In a brake lever fulcrum, a lever mounting part, and a beamattachment part, which latter is preferably and adjustably connected tothe former, so as to accommodate differently positioned rivet holes.

11. In a brake lever fulcrum, a lever mounting part and a beamattachment part, which latter is capable of accommodating itself tovariously positioned rivet openings in the beam.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses, this 2 day of July, 1909.
